Specification of Letters Patent.

Patented Oct. 12, 1909.

Application filed. December 29, 1908. Serial No. 469,740.

To all whom it may concern:

Be it known that I. JosIAH H. SMrrrna citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inTrucks, of which the following is a specification.

My invention relates to improvements in trucks, particularly designedfor use on suspension railways, the object of the invention being toprovidean extremely strong support for the car, which will allow of apivotal movement of the truck and overcome swinging movement of the car.

A further obj ectA is to provide an improved construction of bolsterhaving spring mounting at its ends on the side frames of the truck, andmade at its center with an integral journal, constituting the carsupport. n

A further object is to provide an improved construction of bolsterhaving a central car supporting journal and enlarged rubbing surface tocontact with rubbing surfaces on car supporting hangers, and preventswinging of the car.

A further object is to provide an improved construction of tie-bar,which latter affords mounting for auxiliary wheels normally out ofcontact with the tracks, but in position to assist in supporting thetruck in the event of injury to a wheel or axle, and hence preventfalling of the truck.

With these and other objects in view, the invention consists in certainnovely features of construction, and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings, Figure 1, is a top plan view illustratingmy improvements. Fig. 2, is a view in side elevation partly in section.Fig. 3, is a view in cross section on the line 3-3 of F 2, and, Fig. 4,is a view in end elevation.

prevent lateral movement and buckling of the side frames.

U-bolts 8 straddle the frames 1, at their lower ends, project throughopenings in spring plates 9, and nuts 10 are screwed on to the boltsbelow the plates 9. Coiled springs 11 are supported on the plates 9 andbear upwardly against spring plates 12. Bolts 13 having their upper endscountersunk in the plates 12, extend downwardly ythrough the coiledsprings 11 and plates 9, and through openings in the ends ofsemielliptical springs 14, and nuts 15 are secured on the lower ends ofsaid bolts 13 to eifectnally clamp the ends of the springs 14.

16, 1G, represent tie-bars, which are in the form of flanged castings,having boxes 17 at their ends, secured to the lower ends of the yokeportions 2 of arms 1, by means of bolts 18, and rigidly connect thelower ends of said yokes, constituting a fixed portion of the sideframes. These tie-bars are provided at their center with bearings 19, inwhich the axle stubs 20, of auxiliary wheels 2l, are mounted, and theseauxiliary wheels 21 are preferably positioned, so as to be just abovethe rails and out of contact therewith, but in such close relation tothe track, that should one of the axles, or one of the wheels becomebroken, the auxiliary wheels will come into instant engagement with thetrack,

supporting the truck, and prevent the truck leaving the track.

22 represent-s my improved bolster, which comprises a single integralcasting, having its ends supported at the center of the semiellipticalsprings 14, and secured thereto by means of U-bolts 23. These U-bolts23, there being two employed at each end of the bolster, are each madewith one member longer than the other, the shorter member only extendingup through block 24 on top 'of the springs, and secured by nuts 25 Ewhile the longer members only of said bolts,

l extend'up through the blocks 24, and also 1, 1, represent the sideframes provided with the ordinary yokes 2, receiving the journal box 3,supported on the axles 4, the i latter secured to the ordinary wheels 5.f These frames 1, 1, are connected at their g center by angle irontransoms `6 secured to the frames by means of the angle brackets 7, thelatter', securely riveted to the tranl through the bolster ends, and aresecured by nuts 26. It will thus be seen that the bolts 23 secure thebolster on the springs, and the several sections of the latter together,and that only one member of each U-bolt extends through the bolster,which renders it necessary to remove but four nuts 26 to disconnect thebolster from the truck, and not disturb the other elements of the truckin the slightest. The intermediate portion of said bolster 22 is easthollow and enlarged forming a flat rubbing plate 27, and at the centerthe bolster is made with a tubular post 28 which connects the uppermember of the bolster and the rubbing plate to form a strong and durablestructure. Below the rubbing plate at the center of the bolster, and inline with the post 28, a tubular depending integral journal 29 isprovided on the bolster, and is made with an annular enlargement or head30 at its lower end. This journal 29 is adapted to receive the earhanger sections 3l thereon, said hanger sections being made withsemi-cylindrical bearings at their meeting ends, to encompass thejournal, and provided with flanges 32 at their side edges, which latterare securely clamped by bolts 33, to clamp the hanger around thejournal, and afford a pivotal mounting thereon.

It will be observed that the head is of appreciable greater diameterthan the bearing in the hanger section, and hence there is nopossibility of the hanger falling from the journal.

The hanger sections 3l are both provided with enlargements 34constituting rubbing faces to rub against the enlargements 27 andprevent lateral swinging movement of the hanger sections on the bolster,and compel the springs of the truck to take up all such swingingtendency. rllhe hanger sections 31 may be constructed in a great manyways, those shown straddling the ear body and secured by angle brackets3G to an I- beam `37 extending across the upper portion of the car. TheeXtreme ends of the hanger sections are shown secured by nut-s' 38 toupright bars or rods in the car body.

By constructing improvements as above described, I provide aconstruction of bolster and supporting means for the car body, whichwill prevent any independent swinging movement of the car body on thebolster, and which will absolutely prevent any separation of the earbody from the bolster, but permit a suthcient pivotal connection betweenthem to compensate for the curvatures of the track, and the pivotalmovement of the truck, and I further provide an improved constructionwhich can be readily assembled, which will embody the maximum ofstrength and durability with the mini mum of weight, and which willabsolutely prevent accident, due to a broken wheel or axle.

A great many slight changes might be made in the general form andarrangement of parts described without departing from my invention, andhence I do not restrict myself to the precise details set forth, butconsider myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of my invention.
